SPINDLE.

Specification of Letters Patent.

Patented April 17, 1906.

Application filed April 27,1905. Serial No. 257,676.

To all whom it may concern: I

Be it known that I, JAMES G. EARLE, of Dedham, in the county of Norfolkand State of Massachusetts, have invented certain new and usefulImprovements in Spindles, of which the following is a specification.

This invention has relation to spindles, and has for its object toprovide therein certain improvements, which are illustrated upon theaccompanying drawings, described in the following specification, and setforth in the appended claims.

' Referring to said drawings, Figure 1 represents in section a spindleembodying the invention. Fig. 2 represents an enlarged section throughthe same.

The usual ring-rail with the ring thereon is indicated at a and thespindle-rail at b. In addition I employ what may be termed a step-rail cfor a purpose to be described.

The blade or member (1 has an inverted cup (1 on its lower end and istapered at d to receive a spool or bobbin holder 6 of any ordinary orsuitable construction. The cup d is interiorly threaded to screw uponthe upper mounted to rotate freely and to which is attached theband-driven whirl g. It will be noted that the whirl is located belowthe spindle-rail.

The sleeve f and the member (1 constitute a two-part element which isemployed in lieu of the ordinary spindle-blade and in which the partsare separable, so that members (1 of different lengths or diameters maybe employed. The sleeve f is journaled upon the upstanding rod or stemh, which is supported by the step-rail c. Said rod or stem projectsupward through an aperture in the rail 1) and is provided at twoseparated points with cones h 7L2, respectively. The cone 72/ has afriction-tight fit upon the rod and is in operative relation to a race fat the lower end of the sleeve, so that balls 01 may be interposedbetween them. The cone k is screwed upon the upper reduced and threadedend of the rod and is held orilocked after adjustment by a lock-nut hand a washer 72/, which has a lug extending into a slot h in said rod.Co-

acting with said cone is a race f inserted in the upper end of thesleeve f, and between the cone and the race are the antifrictionballs i.

The lower end of the rod or stem h has a base It, resting upon thestep-rail, and a threaded portion 7L7 extending through an aperture insaid rail to receive a lock-nut k The axes of the rodhand the bladedcoincide.

The sleeve f in addition to being journaled on the rod or stem isjournaled upon the spindle-rail. To this end the rail 1) has an apertureto receive a cup 1', which has a flange j overlapping the surface of therail, as shown. The cup 3' is formed with a race 3' while upon thesleeve f is screwed a cone 7c, so that balls m may be placed betweenthem. This antifriction-bearing serves to support the weight of thespindle-blade, the sleeve, and the whirl, whereas the rod or stem 72,holds said parts against lateral or gyratory movement.

The invention possesses numerous advan tages which will be apparent tothose skilled in the art to which it relates. Among these advantages maybe noted the steadiness and evenness of rotation and the removability ofthe blade with its inverted cup-shapedbase or end.

Having thus explained the nature of the invention and described a way ofconstruct ing and using the same, although without attempting to setforth all of the forms in which it may be made or all of the modes ofits use, I declare that what I claim is- 1. In a spindle, a bearingadapted to be supported by the spindle-rail, a rotatable member mountedin said bearing, a blade supported and rotated by said member, a whirlon said member below the spindle-rail, and an independently-supportedstem on which said rotatable member is journaled to hold it againstlateral or gyratory vibration.

2. The combination with a step-rail and a spindle-rail, of a rod or stemon the step-rail, a bearing on the spindle-rail, and a hollowbobbin-supporting member journaled in said bearing and on said rod orstem.

3. In a spindle, the combination of a rod or stem, a hollow cylinder,said rod or stem and said cylinder being provided with comattached tosaid hollow cylinder.

4. In a spindle, the combination of a rod 5 or stem, a hollow cylinder,said rod or stem and said cylinder being provided with complementalcones and races, balls interposed between said cones and races, a bladeat tached to said hollow cylinder, a cup adapted plemental cones andraces, balls interposed for attachment to a rail and having a race, anI0 between said cones and races, and a blade external cone on saidcylinder and balls between said last-mentioned cone and race.

In testimony whereof I have afliXed my signature in presence of twowitnesses.
